TLDR
In this paper, a particulate product comprising at least one microprojectile is defined as a product consisting of at least two microprojectiles, characterised in that one of them is made of silicon.Abstract:
The invention relates to a particulate product comprising at least one microprojectile; characterised in that the or at least one of the microprojectiles comprises silicon. The invention also relates to devices and components used in the microprojectile implantation of the particulate product to a target of cells or target tissue.read more

Personal care compositions
TL;DR: Aerosolized compositions including a cyclic oligosaccharide; a fragrance; a volatile solvent; and a propellant are described in this article, where the aerosolized composition is free of nonvolatile solvents.
Patent
Method and apparatus for introducing biological substances into living cells
TL;DR: In this article, a "cold" gas shock is used to accelerate microprojectiles, where particles are presented to the gas shock on a planar surface perpendicular to the plane of expansion of the gas wave.
Patent
Gas driven gene delivery instrument
TL;DR: In this article, a gas driven apparatus for accelerating particles (16) coated with a genetic material into a target, comprises a reservoir for releasably retaining a gas at a sufficiently high pressure to detach the particles from the surface of a sample cartridge and to carry the particles through the apparatus (10) toward the target.
